The risks of excess radiation exposure are not insignificant, potentially leading to a variety of health issues, from cataracts and hair loss to birth defects and the development of cancers. Following the best radiation safety practices, therefore, is beneficial both for patients and healthcare workers.
What is radiation safety and why is it important in our field?
Radiation protection aims to reduce unnecessary radiation exposure with a goal to minimize the harmful effects of ionizing radiation. [2] In the medical field, ionizing radiation has become an inescapable tool used for the diagnosis and treatment of a variety of medical conditions.
What is safety radiation?
Radiation safety refers to safety issues related to radiation hazards arising from the handling of radioactive materials or chemicals and exposure to x-ray from x-ray machines, electron microscopes, particle accelerators, atomic energy plants, nuclear explosions or accidents etc..
Why is protection from harmful radiation important to human health?
Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. has sufficient energy to affect the atoms in living cells and thereby damage their genetic material (DNA). Fortunately, the cells in our bodies are extremely efficient at repairing this damage.
Why is radiation safety an important role in nuclear medicine?
The principles of the protection of workers from ionising radiation in all areas of medicine are directed at prevention of deterministic effects and minimization of risk for stochastic effects (cancer).
What are the radiation safety guidelines?
In general, alpha, beta, gamma and x-ray radiation can be stopped by:
- Keeping the time of exposure to a minimum,
- Maintaining distance from the source,
- When appropriate, placing a shield between yourself and the source, and.
- Protecting yourself against radioactive contamination by using proper protective clothing.
What are the benefits of radiation?
Today, to benefit humankind, radiation is used in medicine, academics, and industry, as well as for generating electricity. In addition, radiation has useful applications in such areas as agriculture, archaeology (carbon dating), space exploration, law enforcement, geology (including mining), and many others.
What are the positive effects of radiation?
Vast literature demonstrates that such effects, usually known as hormetic ones, occur at molecular, cellular and population levels, and often result in increase longevity and decreased cancer incidence. Exposure to lower than natural radiation causes deficiency symptoms in protozoa and bacteria.
What is the concept of radiation protection in nuclear medicine?
Radiation protection in nuclear medicine is concerned with the control of both normal and potential exposure of workers in all situations that involve use of unsealed sources of radiation.
What is a source of radiation in the healthcare setting?
Today, in the US, medical procedures from ionizing radiation account for 51% of our average annual dose from radiation (the other 49% is from naturally occurring sources such as cosmic rays, radon, and soils).
